(PDF) Optimum cutting wire assembly in dimension

Diamond wire cutting is the most common method used for rock block production in quarry mining.

Discontinuity modelling and rock block geometry

2018-1-8  Following that, a new method for optimization of block extraction in dimension stone quarries was developed on two scales: a large or quarry scale and a small or quarry-front scale. The large-scale optimization assisted in determining the best quarrying direction, while the small-scale optimization assisted in finding the optimum cutting side locations in a face.

SPT N values shall be corrected for hammer efficiency, if applicable to the design method or correlation being used, using the following relationship. N. 60 = (ER/60%) N (5-1) Where: N = uncorrected SPT value (blows/ft)

Shear strength studies on soil-quarry dust mixtures

2006-10-1  Out of the different quarry wastes, quarry dust is one, which is produced in abundance. About 20–25% of the total production in each crusher unit is left out as the waste material-quarry dust. Bulk utilization of this waste material is possible through geotechnical applications like embankments, back-fill material, sub-base material and the like.
